SPECIFICATION formingpart of Letters Patent No. 718,586, dated January 13, 1903.

Original application filed March 21, 1901, Serial No. 52,231. Divided and this application filed July 30, 1901. Serial No. 70,248. (No model.)

To all whom it may concern:

Be it known that I, EDWARD A. Srrccms, of Beverly, county of Essex, Commonwealth of Massachusetts. have invented certain Improvements in Edge-Gages, of which the following, read in connection with the accompanying drawings, is a specification.

This my improved edge-gage is represented in this instance as arranged to combine IO with the machine shown in United States Letters Patent No. 584,744, dated June 15, 1897. In the accompanying drawings, Figure 1 is a perspective view showing the edge-gage complete. Fig. 2 is a perspective View, partly [5 in section, showing the edge-gage in operation and in operative position. Figs. 3 and 4 are plan views, Fig. 3 showing the gage in contact with the shoe. Figs. 5 and 6 show two different positions of the gage in contact with the shoe. Fig. 7 is a vertical section through the longitudinal center of part 20 and segment-piece 28.

The body 16, arranged to slide on part 12, secured to frame C by screw -bolt 14, the mounting of thethin gage 18 and thick gage 20 on pivot 22 and shoulders 24 and 26, are all as shown in said Letters Patent No. 584,744 and will not be further described herein. Segment-piece 28 has a dovetailed groove, 30 which is entered by a rib 30 on part 20. On segment-piece 28 is secured the contact-piece 32 by pivot 42, this being the part against which the shoe is held by the workman. Rib 30 is formed in the arc of a circle of which 35 the center is the point 34 on contact-piece 32, so that as the segment-piece is moved up or down on rib 30 the position of point 34 is unchanged. Torsional spring 86, secured to pin 38 and bearing at one end on pin 40 in seg- 4o ment-piece 28, normally tends to move the segment-piece downward, and thereby maintain the contact-face of part 32 in its normal position in substantially a vertical plane.

It will be observed that by the foregoing construction I have secured an edge-gage having a contact-piece capable of assuming any position that maybe necessary to follow the contour of the last as the workman moves the shoe around to present all parts of the 'shoe to the action of the lasting mechanism.

This construction also will enable the workman to vary the angle at which he holds the shoe, as he may desire, without changing the adjustment of the edge-gage.

This edge-gage is particularly adapted for use in connection with the mechanism described and claimed in application for United States Letters Patent, Serial No. 52,231, filed March 21, 1901, of which application this present application is a division.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. An edge-gage comprising a support, a segment-piece movable in the arc of a circle on said support, and a contact-piece pivoted on said segment-piece.

2. An edge-gage, means to support said gage whereby itis capable of universal movement and means for normally maintaining the contact-face of said gage in a substantially vertical plane.

3. An edge-gage, means to support said gage whereby it is capable of universal movement and means to maintain the upper edge of the contact-surface of said gage in sub stantially the same horizontal plane.

4. An edge-gage comprising a support, a segment-piece, movable on said support in an arc of a circle, and a contact-piece mounted on said segment-piece and having the center of said are located in its contact-surface.

5. An edge-gage comprisinga support having a rib, a segment-piece having a groove to fiton said rib, a; contact-piece on said segment-piece and a spring tending to maintain said contact-piece in normal position.

EDWARD A. STIGGINS.
